How to Fix CVE-2021-40829

To remediate this vulnerability, upgrade all affected Aws iot device sdk dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

software.amazon.awssdk.iotdevicesdk:aws-iot-device-sdk fixed: 1.4.2 
<dependency>
    <groupId>software.amazon.awssdk.iotdevicesdk</groupId>
    <artifactId>aws-iot-device-sdk</artifactId>
    <version>1.4.2</version>
</dependency>
aws-iot-device-sdk-v2 fixed: 1.5.3 
npm install aws-iot-device-sdk-v2@1.5.3
awsiotsdk fixed: 1.6.1 
pip install awsiotsdk>=1.6.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=software.amazon.awssdk.iotdevicesdk

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2021-40829, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=software.amazon.awssdk.iotdevicesdk

Analyze the terminal output to locate any version of Aws iot device sdk in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.4.2), your application is affected.

Note: The mvn dependency:tree -Dincludes=software.amazon.awssdk.iotdevicesdk command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-295: Improper Certificate Validation, where the product does not validate, or incorrectly validates, a certificate. In Aws iot device sdk, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Connections initialized by the AWS IoT Device SDK v2 for Java (versions prior to 1.4.2), Python (versions prior to 1.6.1), C++ (versions prior to 1.12.7) and Node.js (versions prior to 1.5.3) did not verify server certificate hostname during TLS handshake when overriding Certificate Authorities (CA) in their trust stores on MacOS. This issue has been addressed in aws-c-io submodule versions 0.10.5 onward. This issue affects: Amazon Web Services AWS IoT Device SDK v2 for Java versions prior to 1.4.2 on macOS. Amazon Web Services AWS IoT Device SDK v2 for Python versions prior to 1.6.1 on macOS. Amazon Web Services AWS IoT Device SDK v2 for C++ versions prior to 1.12.7 on macOS. Amazon Web Services AWS IoT Device SDK v2 for Node.js versions prior to 1.5.3 on macOS. Amazon Web Services AWS-C-IO 0.10.4 on macOS.
